2. A patient with type 1 diabetes mellitus is admitted with hyperglycemia and associated acidosis. The presence of which alternative fuel in the body is responsible for the acidosis?

a)	Glycogen
b)	Insulin
c)	Ketones
d)	Proteins

 

 

ANS:  C

When fats are converted to ketones for use as alternative fuel, as in diabetic ketoacidosis when glucose cannot by used by the cells, the acidity of the blood rises, leading to the acidosis. Glycogen is converted to glucose to meet energy needs. Insulin, a pancreatic hormone, promotes the movement of glucose into cells for use. Proteins would not be used for fuel as long as fats were available.

4. Which polysaccharide is stored in the liver?

a)	Insulin
b)	Ketones
c)	Glycogen
d)	Glucose

 

 

ANS:  C

Humans store glucose in the liver as polysaccharides, known as glycogen. Glycogen can then be converted back into glucose to meet energy needs through a process known as glycogenolysis. If fats must be used for energy, they are converted directly into ketones. Insulin is a pancreatic hormone that promotes the movement of glucose into cells.
